Ratiometric fluorescence detection of pyrimidine/purine transversion by using a 2-amino-1,8-naphthyridine derivative.
A new class of abasic site-binding fluorescence ligands, Naph-NBD in which 7-nitrobenzo-2-oxa-1,3-diazole (NBD) is connected to 2-amino-7-methyl-1,8-naphthyridine (Naph) by a propylene linker, is presented for the ratiometric assay for SNPs typing. In solutions buffered to pH 7.0 (I = 0.11 M, at 5 degrees C), Naph-NBD is found to selectively recognize pyrimidine bases over purine bases opposite...
متن کاملFluorescence and electrochemical detection of pyrimidine/purine transversion by a ferrocenyl aminonaphthyridine derivative.
A novel hydrogen bond-forming ligand for pyrimidine/purine transversion, which contains both a fluorescent naphthyridine moiety and a ferrocenyl group as an electrochemical indicator, is described. Hydrogen bond-mediated recognition for a target nucleobase at an abasic site in a DNA duplex is confirmed by both fluorescence and electrochemical measurements. The analysis by fluorescence titration...
متن کاملSelective and sensitive detection and quantification of arylamine N-acetyltransferase 2 by a ratiometric fluorescence probe.
A novel NAT2 specific probe has been developed for sensitive detection of the activity of NAT2. Upon NAT2 catalyzed acetylation of the molecule to N-acetyl-amonafide, the ratiometric response of fluorescence with significant changes in wavelength and intensity is observed. Its significant application potential has been successfully demonstrated in cellular systems.
متن کاملSynthesis and evaluation of fluorogenic 2-amino-1,8-naphthyridine derivatives for the detection of bacteria.
Several novel fluorogenic N-aminoacylnaphthyridine substrates were synthesized in good yield and tested for their ability to detect pathogenic bacteria in agar-based cell culture. Simple 2-N-(β-alanyl)amino-5,7-dialkylnaphthyridine substrates were selectively hydrolysed by β-alanylaminopeptidase expressing bacteria, but were subject to diffusion in the agar medium. Diffusion was reduced in the ...
متن کاملextremal region detection guided by maxima of gradient magnitude
a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
